OOP implementation in Next Generation Shell was inspired by CLOS but it's way simpler. Defining a type: type MyType. At any point one can declare method: F myMethod(..., mt:MyType, ...) some_code() Anything defined by F is automatically a multimethod. When invoked, all methods in the multimethod are searched bottom up. The first one where the call arguments match the parameters (by type, with inheritance) is invoked. That's roughly it.
